LOW POWER DETECTION OF WIRELESS POWER DEVICES |
| 摘要 |
Exemplary embodiments are directed to detection and validation of wirelessly chargeable devices positioned within a charging region of a wireless power transmitter. A device may include a detection circuit comprising an oscillator, the detection circuit configured to detect a change in a frequency of the oscillator. The device may also include a wireless power transmitter configured to determine whether a chargeable device is positioned within a charging region of the transmitter upon the detection circuit detecting the change in the frequency of the oscillator, wherein the transmitter further configured to be selectively electrically isolated from the detection circuit. |
